Naming should be changed:

coded_vertex_flag -> coded_res_flag quotient -> res_coeff_q remainder -> res_coeff_r sign -> res_coeff_s

in TEncGOP.cpp, there is

for( UInt i = 0; i < MAX_LAYERS; i++ ) {

m_ppcTEncTop[i]->setPocDecrementedInDPBFlag(false);

}

this loop should be restricted to number of initialized "m_ppcTEncTop"s. Say , it is better to verify if (m_ppcTEncTop[i] != NULL)
